6、Right.Please tell me what can be used as Predicate according to these examples.One student,one sentence.S1:In the first sentence,its predicate is a transitive verb.S2:The predicate of the second sentence is an intransitive verb.S3:In Sentence 3 and Sentence 4,they have the same verblink verb.Their p

7、redicates are a link-verb plus a predicative.S4:The predicate of the fifth sentence is a phrasal verb.S5:The structures of the sixth and the seventh sentences are the same.Their predicates are an auxiliary verb plus a notional verb.S6:The predicates of Sentence 8 and Sentence 9 are a modal verb plus

8、 a notional verb.Step PracticeT:Now lets do some exercises.Fill in the blanks with the proper forms of the verbs in the brackets.You should pay attention to the tenses and the agreement between the Subject and the Predicate.Discuss them with your partners.A few minutes later,Ill check your answers.(

9、Show the following on the screen.)Fill in the blanks with the proper verb forms:1.An iron and steel works,with some small factories, _ (be) to be built here.2.Every boy and every girl_ (wish) to attend the evening party.3.The crew _ (be) standing in different parts of the ship.4.One and a half apple

10、s _ (be) left on the table.5.The German and the English language _ (have) something in common.6.A variety of questions _ (be) put to the lecturer.7.Another five weeks_ (be) necessary for us to finish the work.8.What they have done_ (be) useful to the people.9.In the room _ (be) found a big table and

11、 a great many chairs. (A few minutes later.)T:Have you finished?Ss:Yes.T:Please give us your answer to each sentence and tell us your reason briefly if you can.One student,one sentence.Any volunteers?S7:1.The answer to the first sentence should be “is”.The reason is that its Subject is “an.works” an

12、d “iron and steel” are used as the Attribute,so we should choose a singular verb.S8:2.Though the two subjects are joined by “and”,they are each preceded by “every”.A singular verb is needed here.So we use “wishes”.Am I right?T:Do you agree with him,so?Ss:Yes.He is right.S9:3.Here we use “were” as it

13、s predicate.Because “crew” is a collective noun and should take a plural verb.S10:4.“One and a half” takes a plural noun but a singular verb,so we use “is” as its predicate.S11:5.I think its predicate should be “have”.When a singular noun is modified by two adjectives so as to mean two distinct thin

14、gs,the verb should be in the plural.S12:6.We choose “were”.Because the Subject is “questions”.S13:7.Its predicate should be “is”.Because plural expressions of time,distance,weight,value,ect.usually takes a singular verb.S14:8.When the Subject is expressed by a phrase or a Subject clause,the verb is

15、generally in the singular.So we take “is” as its predicate.I remember I read a sentence “what we badly need here are teachers.”Is it right or worng?T:Its right.“What-clause” is used as Subject,if its predicative is a plural noun,we generally choose a plural verb as its predicate.Are you clear about

16、that?Ss:Yes.S15:9.Im not sure of choosing “were” or “was”.Can you explain it to me?T:Generally speaking,here a plural verb is right.However,there is a strong tendency to use the verb in the singular form instead of the plural in the inverted construction when the first Subject that follows the verb

17、is singular.So both “were” and “was” here are right.Have you any questions?(Teacher answers any questions raised by the students.)Step PracticeT:Now well do another practice.Look at the screen and choose a suitable modal verb for each blank.Have a discussion with your partner and write down your ans
